Description: Tracks the count of active IKE and IPsec security associations on Juniper NetScreen VPN gateways.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is NETSCREEN-VPN-MON-SA-COUNT-MIB?
NETSCREEN-VPN-MON-SA-COUNT-MIB is a Juniper NetScreen ScreenOS MIB module that tracks the count of active IKE and IPsec Security Associations (SAs) on NetScreen VPN gateways. No detailed sample objects were provided, but a MIB of this purpose would expose a table of SA count entries, likely broken out by SA type (IKE Phase 1 vs. IPsec Phase 2) and possibly by virtual system, reflecting current VPN tunnel load. Its monitoring value is directly tied to VPN service/software status — a sudden drop in active SA counts can indicate tunnels going down or a gateway failing to renegotiate, while an unexpectedly high count could signal capacity pressure. It depends on the NETSCREEN-SMI enterprise tree for its OID placement and relates conceptually to the broader NetScreen VPN feature set. It is deployed on Juniper NetScreen VPN gateway appliances in site-to-site or remote-access VPN deployments where tunnel/SA capacity and health need tracking. Engineers can download the NETSCREEN-VPN-MON-SA-COUNT-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in NETSCREEN-VPN-MON-SA-COUNT-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Juniper NetScreen VPN gateway appliance
Monitoring Examples
No sample objects were provided beyond the general concept of 'a list of SA count entries,' so a specific object-grounded polling walkthrough can't be honestly constructed; the plausible use, based on the module's stated purpose, is polling a table of active IKE/IPsec SA counts to detect tunnels dropping or gateway capacity limits being approached, but this is inferred rather than confirmed against actual object names.
